macOS command file to run DOSBox Staging on a particular DOS program

macos_launch.command

#!/bin/sh
# Yes, POSIX shell. Because I said so.
#
# Example: run Wing Commander 1 launcher

COMMAND="LAUNCHER.BAT"

MYDIR=$(dirname -- $0)
nohup /Applications/DOSBox\ Staging.app/Contents/MacOS/dosbox  -exit ${MYDIR}/${COMMAND} 2> /dev/null > /dev/null &

# The magic incantation to:
# a. Make Terminal willing to close windows
# b. Quit the terminal after this .command file runs
# c. Get rid of Terminal from the Recent Apps list (because nobody runs Terminal)
#
# We're being clever with subshells here because Terminal doesn't want to die.
#
# Terminal is a piece of shit.
#
# a. Fuck this default pref of leaving dead windows.
defaults export com.apple.Terminal - \
    | plutil -replace "Window Settings".Basic.shellExitAction -integer 1 -o - - \
    | defaults import com.apple.Terminal
  
# b. call applescript host to kill the fucking terminal, which will now die.
( sleep 1;  osascript -e 'tell application "Terminal" to quit' 2> /dev/null >/dev/null & )

# c. Get rid of the ugly and confusing icon. Requires dockutil. Skipped if not present.
if [ $(which dockutil) ] ; then
    ( nohup dockutil --remove Terminal 2> /dev/null > /dev/null & )

# TODO: just make command files only ever run in iTerm. Except iTerm pops a tab instead of
# a window which is hot garbage. Tabbed terminal windows are trash.
